Spontaneous Rat Nonthymic T Cell Lymphoma 329 Table 2. In search of an adequate model for the human metabolic syndrome, the metabolic characteristics of Wistar rats were analysed after being submitted to different protocols of high fructose ingestion. Materials and Methods. Characteristics of open field behavior of Wistar and Sprague-Dawley rats. Reece WO. Gut microbiota remains a prominent source for a diverse range of potential probiotics. The best-known Rattus species are the black rat (R. rattus) and the brown rat (R. norvegicus).The group is generally known as the Old World rats or true rats and originated in Asia.Rats are bigger than most Old World mice, which are their relatives, but seldom weigh over 500 grams (1.1 lb) in the wild.. Taxonomy of Rattus Silver nanoparticles have found wider and increasing biomedical applications due to their broad antimicrobial characteristics. Physicochemical characteristics of CNSO demonstrated high percentage oil yield, low saponification value, elevated acid and free fatty acid … The open field test (OFT) was carried out on Wistar and Sprague-Dawley rats between the ages of 3 to 20 weeks. Rat, (genus Rattus), the term generally and indiscriminately applied to numerous members of several rodent families having bodies longer than about 12 cm, or 5 inches. Immunohistochemical Characteristics of Thymomas and Hyperplastic Lesions in Wistar Hannover Rats Toxicol Pathol. All these tumors were examined microscopically, and the morpho- logical characteristic described (Table I). 2Department of Veterinary Surgery and … The OFT scores varied depending on the day and the age. Background: The Goto-Kakizaki (GK) rat, developed from repeated inbreeding of glucose-intolerant Wistar rats, has been widely used to explore the development of spontaneous type-2 diabetes mellitus (T2DM). Characterization a model of prostatic diseases and obstructive voiding induced by sex hormone imbalance in the Wistar and Noble rats. The absence of a diuretic effect of prostaglandins on the kidneys was accompanied by structural changes in the transepithelial and interstitial barriers for an osmotic flow of water. However, the gastric microbiota of GK and Wistar rats are still unclear. Characterization of Coronavirus JHM Variants Isolated from Wistar Furth Rats with a Viral-Induced Demyelinating Disease VINCENT L. MORRIS,*,’ CHRlSTlNATIESZER,* JOANNE MACKINNON,* AND DEAN PERCYt *Department of Microbiology and Immunology, University of Western Ontario, London, Ontario, Canada N6A 5C 1, and tDepartment of Pathology, Ontario Veterinary College, University of Guelph, … Background: Chronic nonbacterial prostatitis associated with lower urinary tract symptoms (LUTS) is a prevalent condition in men. Ulceration and necrosis of the over- lying skin was commonly observed with rap- idly growing masses. Adult male Wistar rats were exposed to repeated doses of NGO for 15 days and 30 days. of rats in the USA. Monoclonal Antibodies Against 0x7 W3/13 OX8 W3/25 OX4 0x12 Organ Nikolskaia, K., Eshchenko, O., & Shpinkova, V. (1997). Morphological characteristics of the inner medullary zone in the kidneys in Brattleboro and Wistar rats were studied during blockade of prostaglandin synthesis. Epub 2020 Jun … Male Wistar Rats (n = 48, initial body weight: 115.30 ± 1.73 g) were allocated into 4 groups (n = 12/group) and received one of the following diets: Normal sodium normal fat (NSNF), normal sodium high fat (NSHF), high sodium normal fat (HSNF), high sodium high fat (HSHF) diet for 12 weeks. Sixteen lactic acid bacteria (LAB), from rectal swab of Wistar rats, were subjected to evaluation of probiotic properties. Here, we evaluated the physicochemical characteristics as well as acute and subacute toxicity of the CNSO in rats. Asano Y. Zemjanis R. Collection and evaluation of semen. [The characteristics of exploratory behavior in Wistar rats in a permanent inhomogeneous magnetic field]. First, two adult rat groups (aged 90 d) were studied: a control group (C1; n 6) received regular rodent chow (Labina, Purina) and a fructose group (F1; n 6) was fed on regular rodent chow. Body weight (BW) and food intake (FI) were measured weekly. 27. •The Wistar bloodline has contributed more strains of rats than any other line. Following primary and booster immunization, female Wistar rats developed severe arthritis, with an incidence of >83% and low variability in clinical signs. 26. Gonadosomatic index and spermatozoa morphological characteristics of male Wistar rats treated with graded concentration of Aloe vera gel. [The characteristics of exploratory behavior in Wistar rats in a permanent inhomogeneous magnetic field]. Baltimore, MD: William and Wilkins Company, 1970:242. In: Diagnostic and therapeutic techniques in animal reproduction. Enzyme activities in the sensorimotor cortex did not change. A total of 374 mammary tumors and 106 hyperplastic lesions were identified in female rats, five tumors were found in male rats. At that time, the behavior of each naive rat was observed for two 3-minute periods separated by an interval of 24 h (Day). 2nd Ed. Species and description. The results demonstrated that Wistar rats were the most susceptible strain to CIA followed by Wistar Furth rats, with Sprague Dawley rats being the least susceptible. (Smaller thin-tailed rodents are just as often indiscriminately referred to as mice.) the rat. Characteristics of Open Field Behavior of Wistar and Sprague-Dawley Rats Yuzo ASANO Safety Research Laboratory, Tanabe Seiyaku Co., Ltd., Kashima 3-16-89, Yodogawa-ku, Osaka 532, Japan (Received 31 January 1986/Accepted 2 May 1986) The open field test (OFT) was carried out on Wistar and Sprague-Dawley rats between the ages of 3 to 20 weeks. The effect of oleanolic acid on sperm motion characteristics and fertility of male Wistar rats M. C. Mdhluli1& G. van der Horst2 1Diabetes Research Group: Primate Unit, South African Medical Research Council, PO Box 19070, Tygerberg 7505, South Africa and2Physiological Sciences Department, University of the Western Cape, P=Bag X17, Bellville 7535, South Africa Thus, the findings in the female Wistar rat CIA model closely resemble the disease characteristics of human RA. 2020 Jul;48(5):649-655. doi: 10.1177/0192623320922849. Doctor of Philosophy . The specific objectives of the present study were accordingly as follow: (1) to establish an experimental model of TBBPA particle inhalation exposure using Wistar rats; (2) to investigate the excretion characteristics of inhaled TBBPA dry-powder following mouth and nose inhalation exposure; and (3) to investigate the concentration of TBBPA in serum following inhalation exposure over a 14-d … Background . 2011 . Spermatozoa morphology and characteristics of male wistar rats administered with ethanolic extract of Lagenaria Breviflora Roberts Adebowale Bernard Saba1*, Olayinka Ayotunde Oridupa1, Matthew Olugbenga Oyeyemi 2 and Oluwaseun Dapo Osanyigbe1 1Department of Veterinary Physiology, Biochemistry and Pharmacology, University of Ibadan, Nigeria. He later established Wistar Institute in Philadelphia that will have a major role in the development of the rat as an important laboratory animal similar to the impact the Jackson laboratory had on the development of the laboratory mouse. Immunohistochemical characteristics of lymphocytes from formalin-fixed sections of bone marrow and lym- phoid tissues of normal Wistar rats. Characteristics of Metabolic Syndrome in Wistar Rat Dams and their Offspring . Objectives . However, toxicity of nanoparticles is a subject of continued controversy, thus necessitating further studies in this direction. Quantitative cytochemical assay showed that single injection of delta sleep-inducing peptide increased monoamine oxidase activity (substrates: serotonin and tryptamine) in the caudate and accumbens nuclei and glutamate dehydrogenase activity in the hippocampus of stress-resistant Wistar rats chronically treated with L-DOPA. Department of Nutritional Sciences University of Toronto . One potential pathophysiological factor is change in sex hormone, testosterone and estrogen, balance. This study investigated the biochemical effects of silver nanoparticles in Wistar rats. The spermatozoa characteristics of Wistar rats in Groups A (control), B treated with chloramphenicol for 20 days and C treated with chloramphenicol for 25 days are as presented in Table I. Motility in the control experiment (Group A) was 89.0 ± 2.45%, which is higher than Group B (72.0 ± 3.74%) and Group C (66.0 ± 2.45%). Sandra Alicia Reza López .
